Thanks guys,
I ever thought of the throttle linkage as I as thinking along the lines of anything but.
I'll have a closer look at that as soon as time allows.

The distributor was rebuilt 20K mi. ago and at that time the person that did the work (no names for now) advised that I set the timing at 16 to 20 BTDC. I've continued to set the timing as per Bentley but often wondered what would be the result of setting the timing at 16 to 20 BTDC.

For now I'll deal with the throttle linkage and take it from there.
thx again
